Grades Classification Of Aluminum And Their Application

1、Grade 1000 Aluminum Sheet

    As we known the pure aluminum, 1000 brand of aluminum in all series belong to a series with the largest amount of aluminum.Purity can reach above 99.00%.Since there are no other technical elements, the production process is relatively simple and the price is relatively cheap, which is the most commonly used series in the conventional industry at present.Most of the products in market are 1050 and 1060 series.The minimum aluminum content of this series is determined according to the last two Arabic numerals of series 1000, for example, the last two Arabic numerals of series 1050 are 50. According to the principle of international brand naming, aluminum content must be up to 99.5%.China’s aluminum alloy technical standard (GB/t3880-2006) also clearly stipulated that the content of 1050 aluminum can reach 99.5%. The same reason is that the content of 1060 series aluminum plate must reach more than 99.6%.

2、Grade 2000 Aluminum Sheet

    The aluminum plate representing 2A16 (LY16) 2A06 (LY6) 2000 series character is high hardness, among which copper content is the highest, about 3-5%.The 2000 series aluminum plate belongs to aviation aluminum material, is not often used in the conventional industry.Our country produces 2000 series aluminium plate manufacturer is less.The quality cannot be compared with that of foreign countries.The imported aluminum sheet is mainly supplied by American and German manufacturers.With the development of China’s aerospace industry, the production technology of 2000 series aluminum sheet will be further improved.

3、Grade 3000 Aluminum Sheet

    Grades of 3003, 3004 and 3A21 is known mainly.Also known as anti-rust aluminum plate China’s 3000 series of aluminum plate production process is relatively excellent.Series 3000 aluminum sheet is made of manganese.The content is between 1.0 and 1.5.Is a rust – proof function of a better series.Conventional application in the humid environment such as air conditioning, refrigerator, car bottom, the price is higher than 1000 series, is a more commonly used alloy series.

4、Grade 4000 Aluminum Sheet

    Aluminum plates representing 4A01 4000 series belong to the series with high silicon content.The silicon content is usually between 4.5-6.0%.Belonging to building materials, mechanical parts, forging materials, welding materials;Low melting point, good performance in corrosion resistance also with heat and wear resistance.

5、Grade5000 Aluminum Sheet

    Brand of 5052.5005.5083 and 5A05 .The 5000 series aluminum plate belongs to the commonly used alloy aluminum plate series, the main element is magnesium, containing magnesium content between 3-5%.Also known as aluminum magnesium alloy.Its main features are low density, high tensile strength and high elongation.Aluminum and magnesium alloys weigh less than other series under the same area. Therefore, they are often used in aviation, such as aircraft fuel tanks.It is also widely used in conventional industries.The processing technology is continuous casting and continuous rolling, which belongs to hot rolled aluminum plate series.China’s 5000 series of aluminum plate is a relatively mature series of aluminum plate.

6、Grade 6000 Aluminum Sheet

    Brand 6061, it mainly contains magnesium and silicon. Therefore, it focuses on the advantages of 4000 series and 5000 series.Good usability, excellent interface features, easy coating, good processing.Can be used on low-pressure weapons and aircraft connectors.General features of 6061: excellent interface features, easy coating, high strength, good usability and strong corrosion resistance.

    Typical USES of aluminium: aircraft parts, camera parts, couplers, ship fittings and hardware, electronic fittings and fittings, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical fittings, valves and valve parts.

7、Grade 7000 Aluminum Sheet

    Brand 7075 mainly contains zinc elements.Also belong to the aviation series, is copper alloy, aluminum and magnesium zinc is heat treatable alloys, belongs to hard aluminum alloy, have good wear resistance. 7075 aluminum plate is by eliminating stress, not deformation, warping after processing. All the 7075 super ultra thick aluminum plate by ultrasonic detection, can guarantee without sand holes, impurities. 7075 aluminum sheet of high thermal conductivity, can shorten the molding time, improve work efficiency.The main characteristic is that the hardness is high 7075 is the high hardness, the high strength aluminum alloy, is often used in the manufacture aircraft structure and the futures.It requires high strength, corrosion resistance of high – stress structural parts, mold manufacturing.Basically rely on import, our country’s production technology still needs to be improved.(a foreign company once raised the problem of uneven annealing of homemade 7075 aluminum plates and inconsistent surface and internal hardness.

8、Grade 8000 Aluminum Sheet

    More commonly used is 8011 belonging to other series.As far as I can remember, aluminum plates are mainly used for making bottle caps. They are also used for radiators, most of which are made of aluminum foil.Less commonly used

9、Grade 9000 Aluminum Sheet

    It belongs to the spare series, which is so developed in science and technology. In order to cope with the emergence of aluminum plates containing other alloy elements, the international aluminum plate belt federation has indicated that the 9000 series is the spare series, waiting for the emergence of another new variety to fill the blank of the 9000 series.
